Abstract : The pail yellow fulgide 7 was prepared via two successive stobbe condensation of one equivalent of diethyl succinate and two molar equivalents 0f 3,5-dimethoxybenzaldehyde. The pail yellow fulgide 7 in booth solid and solution turned pink when irradiated with 366 nm light. The fulgide 7 was found to undergoes a Knovenagel type reaction when condensed with malononitrile under basic condition to give after ring closure the dicyanomethylene derivative 14. The later on irradiation with 366 nm gave the infrared active 1,8a-DHN derivative 16. The 1,8a-DHN derivative of fulgide 7 (e.g. 15) showed remarkable positive solvatochromism as the solvent polarity is increased.
